ASTM A453 GRADE 660 CLASS A Stud bolt with Heavy Hex Nuts
We are professional ASTM A453 GRADE 660 CLASS A Stud bolt with Heavy Hex Nuts manufacturer in China.
ASTM A453 is covering high-temperature bolting materials for use in pressure vessels, valves, flanges, and fittings operating at elevated temperatures.
Grade 660 also known as “Super Alloy” or “A286” stainless steel, a precipitation-hardenable super-alloy based on iron. The material can be used in requiring high strength, paired with corrosion resistance up to 1300 °F (700 °C). it can work at the low-temperature conditions [down to -320 °F (-196 °C)]
There are 4 classes,Class A, Class B, Class C, Class D, Each class has specific requirements for chemical composition, mechanical properties, and heat treatment.
